The one-third of people with the highest cholesterol levels were 57% less likely to get Parkinson’s during a 20-year follow-up compared to the one-third of people with the lowest cholesterol levels according to a recent study.

The one-third of people with the middle cholesterol levels were 44% less likely to get Parkinson’s compared to the one-third of people with the lowest cholesterol levels.

The say this the other way, the one-third of people with the lowest cholesterol levels were 2.3 times more likely to get Parkinson’s than the one-third of people with the highest cholesterol levels, and they were 1.8 times more likely to get Parkinson’s compared to the one-third of people with the middle cholesterol levels.

“Our study suggests that lowering cholesterol unnecessarily actually may harm the brain,” Xuemei Huang, MD, PhD lead author of the study was quoted as saying.
